Ultra-Aire MD33

The Ultra-Aire MD33 is the first true in-wall dehumidifier that features a slim profile of only 5 ¾″ deep, allowing it to easily fit inside 2″ x 6″ or through 2″ x 4″ interior stud walls. A mounting kit is available to affix the unit to masonry and CMU block as well.

The Ultra-Aire MD33 is Energy Star® Certified and runs independent of the HVAC system, removing up to 33 pints of water a day. Sized for up to 1,200 square feet, the MD33 is the perfect solution to control moisture in multi-family applications and features a digital RH control behind a tamper-proof cover.

The unit can be hardwired into existing electrical or directly plugged into a 110v outlet with the provided cord. Designed to drain directly into a hub-drain or plumbing line, the MD33 is truly a hands-off dehumidification system.
